I don't know what you're asking for. Cygwin does provide case sensitive
environment variables.

In a cmd.exe window:

        C:\>set env_var=lowercase
        C:\>set
        [...]
        env_var=lowercase
        [...]
        C:\>set ENV_VAR=UPPERCASE
        C:\>set
        [...]
        env_var=UPPERCASE
        [...]
        C:\>cygwin
        $ set | grep -i env_var
        ENV_VAR=UPPERCASE
        $ logout
        C:\cygwin\bin>exit

And in cygwin's bash:
        $ env_var=lowercase
        $ ENV_VAR=UPPERCASE
        $ set | grep -i env_var
        ENV_VAR=UPPERCASE
        env_var=lowercase
        $ bash
        $ set | grep -i env_var
        $ exit
        $ export env_var ENV_VAR
        $ bash
        $ set | grep -i env_var
        ENV_VAR=UPPERCASE
        env_var=lowercase
        $ exit
        $ cmd.exe
        Microsoft Windows 2000 [Version 5.00.2195]
        (C) Copyright 1985-2000 Microsoft Corp.

        C:\>set
        [...]
        ENV_VAR=UPPERCASE
        [...]
        env_var=lowercase
        [...]

As cfg said: "Don't start the program from a non cygwin program"
